A method is presented that combines advanced experimental and numerical techniques in the determination of constitutive parameters. The general principle is that a specimen, producing a non-homogeneous stress state, is deformed rapidly. Load and deformation is recorded during the deformation and the event is also simulated using FEM. For the numerical calculation a set of constitutive parameters is used which can be systematically adapted so that a good agreement with experimental results is achieved. Strain rates of 10 exp 4 - 10 exp 5 s exp -1 are possible because the specimen can be made small. Microscopic high-speed photography is used to record the deformation of specimens of sub millimetre size. The method allows both tensile and compressive testing.
